Arguments Against Psychological Theories being Sound

• Some Psychology doesn’t predict anything. Psychoanalysis tends to explain an individual’s behaviour after an event which isn’t very useful in predicting behaviour. Humanistic Psychology does not try to have sound theories or hypotheses.
• Humanistic Psychologists argue that each individual is unique and they would rarely try to predict human behaviour.
